Description
このような燃料電池自動車は、燃料の水素をより安全でコンパクトに貯蔵することが重要であり、車両の走行距離を増大させると共に安全性を高める様々な水素貯蔵技術が開発されてきた。このような水素貯蔵技術としては、気体水素を液体水素とする方法や、吸蔵合金に吸蔵させる方法があるが、これは自然蒸発や吸蔵量など現在の技術では解決できない問題がある。
したがって、膨張などタンクの変形状態を考慮せずに水素を高圧に充填する場合、水素タンクの破損、水素の漏洩などにより安全事故が発生する虞があり、走行中に爆発などの大事故を招くことがある。
また、本発明を適用する場合、充填安全性と共に、タンクに対する信頼性を高め、水素タンクに対する全数検査周期を延ばすことができ、検査にかかる費用を低減する利点もある。
本発明は、燃料電池自動車に水素を充填するとき、水素タンクのリアルタイム変形情報を反映して水素をより安全に水素タンクに充填できる水素安全充填システム及び充填方法に関する。
車両側制御部20は、変形測定部10からの電気信号、すなわち水素充填時の変形率信号を受け、これをさらに無線通信手段30に送る。
車両に水素を供給するために、充填所側水素充填器(図1と図2における図面符号「40」)に連結された水素供給ホース44の末端に充填ノズル45が設置されている。そして、車両からのデータを受信するためのIR受信機(32)が、充填ノズル45の一側に設置される。
